Chapter 322: Lao Yu, let’s do our job first
The words were urgent and the tone was affirmative, as if they were afraid that the Seventeenth Machinery Department would hear a wrong word.
No way, this thing is too tempting.
As we all know, we were able to push seventeen countries back to the 38th parallel a few years ago. In addition to command and organization, our traditional close combat and night combat tactics also played an important role.
At that time, the Citizen had almost got a headache at night and his muscles would twist when he heard the charge.
Later, Citigroup even did not hesitate to equip individual night vision devices worth 700,000 dollars a pair. It should be said that it had something to do with the psychological shadow he was hit at this time. Of course, the role played by "Commissioners Smith" was not small. .
It hurts so much, brother!
The leaders of the National Defense Working Committee understand very well that the advantages gained from hard training and excellent organization will be slowly offset by the development of technology. Eventually, one day, if we do not work hard technically, Chasing, this will undoubtedly become our disadvantage.
The sentence "preliminarily intended to be used in line scanning thermal imager imaging sensors" in this thing is exciting enough. He has never heard of a thermal imager, but the term is really pointed. It is so clear that even if you have never heard of it, you can understand what it is the first time you hear it.
This is the wonderful thing about Chinese. Even if it is a new thing, I can give it a name that is easy to understand in a simple and beautiful language.
Coupled with the benefits such as multi-band coverage, working in strong radiation environments, etc., you would be a fool not to have this thing.
The other person sighed: "Okay, I will approve it right away."
Huh? Something's wrong! Hearing this sigh, the leader of the National Defense Work Committee immediately realized that there seemed to be something extra in the matter.
After breaking away from the excitement and thinking deeply, he immediately realized that something was wrong.
Although the Seventeenth Machinery Department is not responsible for the equipment, the significance of this material must not be invisible to the Seventeenth Machinery Department. In this case, he still needs to confirm it from his own side before approving it. Plan, this is interesting.
By the way, what he said earlier is very interesting: "If you think you can slow down a bit," then "I'll suppress it."
This illustrates two problems.
First of all, he was sure that the Defense Working Committee was needed, and the difference was just a matter of sooner or later.
Secondly, he will definitely approve this plan, the difference is only in the time.
It seems that there is content. The National Defense Working Committee couldn't hold back: "Old Y, what's the problem? I hear what you mean, it seems that things are not going very smoothly?"
The Seventeenth Machinery Department did not hide anything: "It's nothing. Gao Zhendong came up with this thing. The reason why I wanted to slow it down at first was because I felt that he had too many things to do and wanted to give him some time to rest. But you can also see Come out, the importance of this thing is really not low, so we should arrange it according to work needs first."
The National Defense Work Committee suddenly realized that this was what happened, and was about to change his mind: " Then just slow down.”
At this point, I can’t talk anymore.
Is slowing useful? Useless!
With Gao Zhendong’s temperament, if you don’t approve of this matter, he will definitely be able to find another thing to fill in for himself.
When the Seventeenth Machinery Department heard this, they laughed: "How is it? You know my difficulty, haha."
"It's difficult!"
The Seventeenth Machinery Department's side Hearing this, he comforted him in turn: "Don't worry too much. I saw that another unit of ours is responsible for the specific implementation of this project, and Gao Zhendong is only responsible for taking the lead. Judging from his habit of working on the previous results, At this point in time, it is estimated that he has completed the principle design part that he should do. It doesn’t make much difference to him whether he takes it slow or not.”
This is reliable. This is the case with single crystal furnaces. Judging from the situation obtained by the 17th Machinery Department, after the project was established, except for the most important principles and original design parts, which Gao Zhendong had already come up with at the beginning, most of the other specific matters were led by him. Comrades are doing it. Unless there are problems, Gao Zhendong doesn't interfere much.
In other words, in addition to temporary issues such as anti-tank missiles, Gao Zhendong himself was involved in things like single crystal furnaces and tungsten-molybdenum alloys. When Gao Zhendong proposed this project, With him, the matter is actually almost complete.
The two of them laughed on the phone, forget it, it's useless to dwell on this, at least Comrade Gao Zhendong's body still looks good, he eats three big bowls in one meal in the cafeteria.
Isn’t his wife about to take the medical examination? When his wife graduates, he will feel more relieved. Both old comrades have begun to put their hopes in what will happen in four or five years.
No matter how you say it, this matter was approved quickly - agreed.
Taking the one from the ministry, a key member led by Yu Yuncheng smiled and said: "There is no comparison between people. Director Gao's application is so simple. He didn't even explain the process. Just follow. It’s enough to just write a name and an introduction. I’m impressed that I can get approved.”
Yu Yuncheng laughed: “If you have the achievements like Director Gao, don’t worry, you will be here.” Just write a few words on the paper and it will still be approved.”
"I don't have any, so I look strange, hehe."
"Why don't you get to work if you know you don't have it! You inform your family and you can make preparations." As for himself, he still has to talk to Gao Zhendong First, communicate the next step of the work. Until now, he himself doesn’t know how to do it.
Seeing him coming over with the report on mercury cadmium telluride, Gao Zhendong smiled and said: "Has it been approved? Then work on your old business for a few days, crystal pulling."< br>
Yu Yuncheng was a little surprised: "Isn't this thing said to be difficult to do? Can it be pulled directly?"
Gao Zhendong smiled: "It's so beautiful. First pull out the quartz tubes and pull out a batch to use as test containers."
The production of bulk crystals of mercury cadmium telluride is basically inseparable from this step. The whole thing is sealed with materials. First make mercury cadmium telluride polycrystalline, but not sealed? Without sealing, you can't even produce mercury cadmium telluride polycrystals.
The one Gao Zhendong chose is even more extreme. All subsequent operations, until the formation of qualified crystals, are performed on this sealed tube.
As for what can withstand the high temperatures and mercury vapor pressure during the manufacturing process? At the same time, without introducing other weird impurities? Is it better to be transparent for easy observation?
Look around, it’s up to you.
——Silica.
So the first step in developing mercury cadmium telluride is to get some high-purity silica crystals to make quartz tubes.
Can you get around it? Maybe you can get around it. Is the price high? Is it effective? It's hard to say why everyone chooses this method over and over again. It's not without reason.
As for the specific crystal pulling process of mercury cadmium telluride crystal, the single crystal furnace is of no use. The main reason is that the current single crystal furnace uses the CZ Czochralski method and cannot pull the mercury cadmium telluride single crystal. .
1761 Institute does not yet have a single crystal furnace, so this matter will naturally have to be done at the third rolling mill for the time being. Fortunately, Yu Yuncheng is familiar with pulling this thing, and it does not take much time.
Yu Yuncheng didn't ask what happened next. He took the specifications of the quartz tube, called his people, and turned around to pull SiO2.
This familiar feeling came back. Director Gao always had a clear goal when explaining things, cutting off details, as if he knew that this road would be successful.
After seeing off the happy Yu Yuncheng, Gao Zhendong started busy with his own affairs.
After the single board computer is finished, you can put it away. This thing is of great use. Just find a way to increase production capacity and reduce costs. You don’t have to worry about it for the time being.
As for the rest of the software improvements, the comrades of the Computing Institute are naturally worried about it. As for the explosion of production capacity itself, isn’t it being done with the 1274 factory? Fortunately, although the Gallic chicken collapsed in the war, it has Business is still real.
Crying Country: What did you say? really? All five missiles were detained.
This, we have to say that the gap between countries is sometimes wider than the gap between people.
The operating system, I have been writing at home, multi-user multi-tasking with network, it is quite time-consuming.
So at this time, what Gao Zhendong was really doing when he was at work was missiles and barrels.
Fortunately, the engine diagram of the missile is almost finished. After the Changjian Factory verifies the propellant, Gao Zhendong can determine what the propellant column in the engine will look like.
The main reason is that although I know the formula and the approximate performance, no one knows whether there is any difference in performance between the X12 made here and the X12 made by Citigroup. This thing is also closely related to the process.
Different combustion temperatures, combustion rates, and detonation heats are quite different in the design of the engine and the design of the charge shape.
The current fixed hair is based on the performance of the original X12 in hand. Maybe when the homemade X12 is produced, these things will be modified to some extent.
So Gao Zhendong changed hands and worked on another thing - the warhead of the tube.
He did not make any modifications to this. He just copied the shape and size of the 89 cartridge. Although there is no clear size, he does have the total length data and front and side cross-section photos of the 89 cartridge. These can be used to complete the battle. The size of the head is pretty much inferred.
Gao Zhendong only drew the warhead itself. As for some connecting parts, fixing pins, etc., he did not draw them. Although these things may seem simple, they are very closely related to actual production and use. He designed this thing himself, which is much longer than that. The sword factory is inferior.
His idea is very simple. This thing is built directly. If the power reaches the expectation, the above trivial matters will be handed over to the Long Sword Factory. It is estimated that the Long Sword Factory is eager for this kind of thing.
Getting an anti-tank missile can also make a baby by the way, but no one will be happy to replace it.
The drawing was done quickly, and then Gao Zhendong called Liu Rongguo. He had already burned the electrodes of the double platinum-rhodium thermocouple. Lao Liang was doing assembly and testing of the thermocouple. Liu Rongguo himself had some time.
